Application filed July 15, 1912. v Serial No. 709,451

To all 1072 amit may concern Be it known that we, ALEXANDER Mo- DOUGALL and ALEXANDER MILLER McDon- GALL, citizens of the United States, residing at Duluth, in the county of St. Louis and State of Minnesota, have invented certain new and useful Improvements in Sea-Going Canal-Boats, of which the following is a specification, reference being had therein to the accompanying drawing.

Our invention relates to improvements in sea-going canal boats.

The object of our present invention is to provide a combination canal and sea-going vessel in which the smoke stack, superstructures and all working parts above the upper deck can be readily removed and lowered within the hull of the vessel so as to enable the boat to pass under low bridges, such as are found spanning ordinary canals.

Another object of our invention is to provide a vessel of this character in which the main or upper deck is straight and parallel with the keel of the vessel from stem to stern, which adds materially to the longitudinal strength of the vessel and to its seaworthiness, and at the same time increases the carrying capacity thereof.

A still further object is to provide a simple cheap and effective boat of this character having certain details of construction hereinafter fully set forth and claimed.

In the accompanying drawings Figure l is a side elevation of a self propelled seagoing canal boat embodying our invention. Fig. 2 is a longitudinal vertical sectional view of Fig. 1, showing the smoke stack, superstructures, and all working parts lowered within the vessel and below the main deck thereof. Fig. 3 is a top plan view of Fig. 2. Fig. 4 is a side elevation similar to Fig. 1, of a vessel not having its own Smotive power, but embodying our invention. Fig. 5 is a vertical longitudinal section of Fig. 4: showing the superstruotures and working parts lowered within the hull of the vessel below the main deck thereof. F ig. 6 is a top plan view of Fig. 5. Fig. 7 is a cross sectional view of our improved vessel such as shown in Figs. 4c, 5 and 6, looking toward the stern. Fig. 8 is a side elevation of the bow of our improved vessel, partly broken away and showing means for raising and lowering the forward superstructures, bollards, etc. Fig. 9 is a transverse sectional view of a canal, showing a bridge of low form and our improved boat passing thereunder.

Referring now to the drawings, 1 represents the hull of our improved double purpose vessel, having the straight upper deck 2, which is parallel with the keel from stem to stern of the vessel and provided with suitable hatches 14: for the handling of the cargo. This straight upper deck greatly strengthens the vessel longitudinally, as compared with the ordinary vessel made high at both ends and low amidships. It

also materially increases the carrying capacity of the vessel and is the simplest and cheapest possible form of construction.

The forward end of both steamer and barge is provided with a removable superstructure or turret 3 having a door 4: upon one side thereof, by means of which entrance may be had to the turret. A hatch, not shown, may also be provided in the top of the turret whereby access may be had to the turret from the top in case of rough weather at sea, there being means of communication with the interior of the hull through the hatch 16, as shown in Figs. 2, 3, 5 and 6 of the drawings. A suitable railing 5 is provided around the upper edge of the turret to protect the sailors, which is well understood. A capstan 17 is mounted upon the upper end of the turret 3 and is removably connected with the Windlass 15 within the compartment 18 below the main deck 2 of the vessel. I

As is understood, the Windlass 15 has suitable steam connections whereby it may be power-operated and thus made to operate the capstan on top of the turret, for the handling of lines, etc, the anchor chains being operated within the compartment 18,

as clearly illustrated, and which operation of they windlass may be controlled either from the top of the turret when at sea, or from within the compartment 18 when navigating canals. Certain auxiliary line handling means accompany the Windlass 15, such as suitable catheads, which are not shown but are common to such devices, and are made use of for handling lines through the exterior Walls of the compartment 18 when the vessel is being manipulatedxwithin canals and under bridges, and, these being operated through the cut-away portion of the bows of the vessel, allow of ample and convenient manipulation of the same, even when. the vessel is broadside against the side of the canal or look. Two pairs of bitts or bollards are mounted upon the turret 3 fore and aft of the capstan, they being for the convenient handling of the lines. 7

A compartment 20 is formed within the hull 1 directly abaft the compartment 18 and covered with a suitable hatch cover 10, preferably the entire size of the compartment, as illustrated in Figs. 2 and 3 of the drawings. This compartment 20 is for the reception of the turret 3 in its entirety when removed from the deck 2 of the vessel when the latter is required to pass under bridges in canal navigation.

In lieu of the compartment 20 we have illustrated in Figs. 4:, 5 and 8 a platform or elevated floor-21 upon which the turret may be placed, if preferred to the compartment 20,the hatchwa-y directly thereover and covered by the hatch cover 10, the same being equally necessary for the passage of the turret 3 in its entirety.

Bollards or bitts 6 are removably mounted upon the deck 2 of the vessel, preferably just forward of the turret 3 when the vessel is at sea, as shown in Figs. 1 and a of the drawings and which may be removed and placed within the compartment l8'when it is necessary to have the deck 2 clear of obstructions, as illustrated in Figs. 2, 3, 5

and 6.

A pilot superstructure or turret 11, similar to theturret 3 is removably mounted upon the deck 2 of the vessel adjacent the stern thereof and, in the case of the steamer,

.just forward of the removable smoke stack 8, but, in the barge, somewhat farther aft,

as clearly illustrated, the steering wheel being indicated at 32. This turret is also provided with a door 7 therein and, whenv on deck, surmounts the hatchway 12 which communicates with the interior of the hull of the vessel and, in the case of the barge, directly with the compartment 22.

' lVithin the hull 1 of the steamer is formed i a compartment 23 just forward of the hatch 12, for the reception of the turret 11, the stack 8 and the life boats 25, the compartment being covered by the large hatch cover We have illustrated a modification of the compartment 23 in the barge, Figs. 4, 5 and 7 in that we have shown a simple platform 26 provided for the reception of the deck elements of the vessel when removed for storage thereupon, if such platform he found more practical. However, we prefer the inclosed compartment 23.

The smoke stack 8 is preferably made in tions may be fitted thereupon vertically and i also conveniently removed and placed below decks when occasion for such arises.

Bitts or bollards 9 are removably mounted upon the extreme after portion of the deck 2 and are arranged to be readily removed and placed within either the compartment 22, as in the barge, '01 in the compartment 13 in the steamer. For convenient manipulation of the movable parts which are at times above the deck 2 and at other times below said deck, as clearly illustrated, we provide portable shears 27 which are a convenient form of derrick for the raising and lowering of the various parts, the tackle 28 being suspended from the shears and readily attachable to such parts as it is desired to-remove.

. Power for operating the tackle 28 is provided for in the form of suitable winches 29, housed within depressed wells 30 within the deck, one just abaft the hatch 10 and one just forward of the hatch 2st, each well being covered with a suitable hatch cover, as is obvious. Thus, when it is desired to remove any of the movable parts of the vessel the hatch covers are removed from the wells 30, the shear 27 erected and line connection made with the tackle 28 to the winch 29, whereby the desired results of lifting and adjusting of the various parts are obtained.

Upon the stern of the barge, illustrated in Fig. 4: of the drawings, we show one set of shears employed as a means of support for the life boat. The same may be so utilized at any time when the deck of the vessel is not cleared away for canal navigation.

From the foregoing it is evident we have provided a practical double purpose vessel in which all of the parts above the uppermost deck of the vessel necessary in its navigati on at sea, may be quickly and easilydisconnected from the deck and loweredwithinthe hull of the vessel, whereby the latter may be readily navigated within restricted canals and pass under bridges with despatch.
